It’s a little hard to tell from the pics, are there any numbers inside the spindle “U” bracket? If not my guess is that it’s a Margay Enduro “clone” that was made by Fox Valley Kart in Lafayette Indiana a few years ago.

Hey Tim; Could you tell me the width of the chassis at the rear of the main tubes? where the bumper plugs into. I actually have a project of my own and im trying to get a baseline of widths of other enduro chassis to see what different sizes people have, new and old!
